Description

Die Erfindung betrifft eine Kippriegelvorrichtung für Drehkippflügel-Fenster und -Türen od. dgl., bestehend aus einer in der verschlußseitigen, unteren Rahmenecke am aufrechten Rahmenholm sitzenden, Riegelstege aufweisenden Kippriegelplatte und aus einem dem verschlußseitigen, aufrechten Flügelholm an der unteren Ecke zugeordneten Riegelglied, das am unteren Ende einer an ihrem oberen Ende über einen Lagerzapfen mit einer Treibstange verbundenden Schwenklasche sitzt, wobei die Schwenklasche mit ihrem Lagerzapfen einen Längsschlitz in einer zur Führung der Treibstange dienenden Stulpschiene durchgreift und wenigstens in der Kippöffnungs-Schaltstellung bei in eine Kippriegeltasche in der Kippriegelplatte eingreifendem Riegelglied zur relativ Stulpschiene, Treibstange sowie Kippriegelplatte für eine begrenzte Schwenkbewegung freigebbar ist, und wobei eine Biegestabfeder mit zwei im seitlichen Abstand voneinander verlaufenden, durch einen Steg miteinander verbundenen Schenkeln einerseits in einer Halterung sitzt und andererseits mit ihren beiden Schenkeln an der Schwenklasche im Abstand von der Achse ihres Lagerzapfens eingespannt ist.The invention relates to a toggle latch device for tilt-and-turn windows and doors or the like, consisting of a toggle latch plate that sits in the lock-side lower frame corner on the upright frame member and has locking bars and from a lock member that is associated with the upright wing member at the lower corner at the lower end of a swivel bracket connected at its upper end via a bearing pin with a drive rod, the swivel bracket with its bearing pin penetrating a longitudinal slot in a faceplate serving to guide the drive rod and at least in the tilt opening switch position when engaging in a tilt lock pocket in the tilt lock plate Locking member for the relative faceplate, drive rod and tilting lock plate can be released for a limited pivoting movement, and a bending rod spring with two legs spaced apart from one another and connected by a web on the one hand i n sits in a holder and on the other hand is clamped with its two legs on the swivel bracket at a distance from the axis of its journal.

Eine Kippriegelvorrichtung dieser Art ist bereits bekannt und beispielsweise in der DE-AS 30 08 556 beschrieben. Sie kann mit ein und derselben Ausgestaltung zur Anwendung bei allen praktisch vorkommenden Kippöffnungswinkeln bei Flügeln zum Einsatz gelangen, dabei jeweils die klapperfreie Halterung des gekippten Flügels sicherstellen sowie die wirksame Blockierung des Treibstangenbeschlages gegen Fehlschaltung bei gekipptem Flügel gewährleisten und darüberhinaus auch als Aushebesicherung für den gekippten Flügel im Bereich der Kippverriegelung wirken.A toggle latch device of this type is already known and is described, for example, in DE-AS 30 08 556. It can be used with one and the same design for use in all practically occurring tilt opening angles for sashes, thereby ensuring the rattle-free mounting of the tilted sash as well as ensuring the effective locking of the connecting rod fitting against incorrect switching when the sash is tilted and also as a safety catch for the tilted sash act in the area of the tilt lock.

Bei dieser bekannten Kippriegelvorrichtung ist die Biegestabfeder vor der Außenfläche der Stulpschiene liegend angeordnet und dabei an ihrem einen Ende mit Abstand oberhalb der Schwenklasche an der Treibstange verankert, während ihr anderes Ende außerhalb der Achse des als Lagerzapfen dienenden Schaftes an der Schwenklasche eingespannt ist.In this known rocker bar device, the bending rod spring is arranged lying in front of the outer surface of the faceplate and anchored at one end at a distance above the swivel bracket on the drive rod, while its other end is clamped outside the axis of the shaft serving as a journal on the swivel bracket.

Die Biegestabfeder benötitgt daher vor der Außenseite der Stulpschiene und oberhalb der Schwenklasche für ihre Unterbringung in jedem Falle einen Freiraum, welcher insbesondere in Längsrichtung der Stulpschiene beträchtlich größer bemessen werden muß, als derjenige Freiraum, welcher an sich für die Längsverschiebung der Schwenklasche relativ zur Stulpschiene erforderlich ist. So wird bei Benutzung der mit der Schwenklasche in Wirkverbindung stehenden Biegestabfeder vor der freien Längsseite der Stulpschiene ein Freiraum benötigt, der eine Länge hat, die gegenüber dem bei alleiniger Benutzung der Schwenklasche benötigten Freiraum in einem Verhältnis steht, das etwa bei 1,6 : 1 liegt. Im Bereich dieses zusätzlich benötigten Freiraumes lassen sich dann aber naturgemäß keine weiteren Funktionsteile vorsehen, wie sie vielfach bei Treibstangenbeschlägen in Gebrauch sind, weil hierdurch nämlich die Wirkungsweise der Biegestabfeder nachhaltig beeinträchtigt werden kann.The bending rod spring therefore requires a free space in front of the outside of the faceplate and above the swivel bracket for its accommodation, which must be dimensioned considerably larger, in particular in the longitudinal direction of the faceplate, than the space which is required for the longitudinal displacement of the swivel bracket relative to the faceplate is. For example, when using the bending rod spring that is operatively connected to the swivel bracket, a free space is required in front of the free longitudinal side of the faceplate that has a length that is in a ratio to the free space required when using the swivel bracket alone, which is approximately 1.6: 1 lies. In the area of this additionally required free space, however, it is then naturally not possible to provide any further functional parts, as are often used in drive rod fittings, because this can have a lasting effect on the mode of operation of the bending rod spring.

Aufgabe der Erfindung ist es, eine gattungsgemäße Kippriegelvorrichtung zu schaffen, bei der nicht nur der für die Unterbringung der Biegestabfeder nötige Einbauraum besser genutzt bzw. verringert, sondern zugleich auch deren Vorspannwirkung verbessert wird. Darüberhinaus sollen aber auch die beim praktischen Einsatz möglichen Verschleißerscheinungen zwischen den zueinander beweglichen Funktionsteilen minimiert werden.The object of the invention is to provide a generic toggle lock device in which not only is the installation space required for accommodating the flexible rod spring better used or reduced, but at the same time its pretensioning effect is improved. In addition, however, the signs of wear that are possible during practical use between the functional parts that are movable relative to one another are also to be minimized.

Die erfindungsgemäße Lösung dieser Aufgabe wird durch die Kennzeichnungsmerkmale des Anspruchs 1, nämlich dadurch erreicht,

  • daß die Biegestabfeder im Längsschlitz der Stulpschiene aufgenommen ist und dabei mit den Längskanten ihrer Schenkel über die Außenseite der Stulpschiene vorsteht,
  • daß die Schwenklasche an ihrer Rückseite mit zwei parallelen Längsnuten versehen ist, in die die Längskanten der Schenkel passend eingreifen, und daß der Längsschlitz an seinen beiden Längskanten im unteren Längenbereich jeweils mit zwei durch eine Nase gegeneinander abgegrenzten Ausbauchungen bzw. Erweiterungen versehen ist, von denen die Schenkel der Biegestabfeder in ihrer entspannten Ruhelage einen Abstand einnehmen.
The achievement of this object is achieved by the characterizing features of claim 1, namely by
  • that the flexible rod spring is received in the longitudinal slot of the faceplate and protrudes with the longitudinal edges of its legs over the outside of the faceplate,
  • that the swivel tab is provided on its rear side with two parallel longitudinal grooves, in which the longitudinal edges of the legs engage appropriately, and that the longitudinal slot on its two longitudinal edges in the lower length region is provided with two bulges or extensions, each of which is delimited by a nose the legs of the flexible rod spring are at a distance in their relaxed rest position.

Aufgrund dieser Ausgestaltung der Kippriegelvorrichtung können die Schenkel der Biegestabfeder mit dem größten Teil ihres Querschnitts innerhalb der Materialdicke der Stulpschiene liegen und nur um ein so geringes Maß über deren Außenfläche vorstehen, daß ein dauerhaft sicherer Formschlußeingriff mit den Längsnuten in der Rückseite der Schwenklasche bei jeder möglichen Schaltstellung derselben erhalten bleibt.Due to this design of the rocker bar device, the legs of the flexible rod spring can lie with the largest part of their cross section within the material thickness of the faceplate and only protrude beyond their outer surface to such a small extent that a permanently secure positive engagement with the longitudinal grooves in the rear of the swivel bracket is possible at all possible Switch position remains the same.

Ein weiterbildendes Erfindungsmerkmal wird nach Anspruch 2 darin gesehen, daß die Biegestabfeder ortsfest bzw. unverschiebbar im Längsschlitz der Stulpschiene aufgenommen und dabei die Schwenklasche mit ihren Längsnuten relativ zu deren Schenkeln gleitbeweglich vorgesehen ist.A further feature of the invention is seen in claim 2 in that the bending rod spring is fixed or immovable in the longitudinal slot of the faceplate and the swivel tab is provided with its longitudinal grooves slidably relative to the legs.

Bewährt hat es sich erfindungsgemäß ferner, wenn nach Anspruch 3 der Steg der Biegestabfeder am oberen Ende des Längsschlitzes der Stulpschiene anliegt, während die freien Enden ihrer Schenkel dem unteren Ende dieses Längsschlitzes zugewendet sind.It has also proven useful according to the invention if, according to claim 3, the web of the bending rod spring rests against the upper end of the longitudinal slot of the faceplate, while the free ends of its legs face the lower end of this longitudinal slot.

Erfindungsgemäß zeichnet sich die Kippriegelvorrichtung nach Anspruch 4 auch dadurch aus, daß die Schenkel der Biegestabfeder in entspannter Ruhelage parallel zueinander verlaufen.According to the invention, the rocker bar device according to claim 4 is also characterized in that the legs of the flexible rod spring run parallel to one another in the relaxed rest position.

Nach Anspruch 5 kann sich dabei der mit den Ausbauchungen bzw. Erweiterungen versehene Längenbereich der Längskanten etwa über die beiden unteren Drittel der Länge des Längsschlitzes erstrecken, wobei nach Anspruch 6 die größte Breite des Längsschlitzes im Bereich der Ausbauchungen zur normalen Breite des Längsschlitzes in einem Verhältnis von etwa 1,25 : 1 stehen kann.According to claim 5, the length region of the longitudinal edges provided with the bulges or extensions can extend approximately over the two lower thirds of the length of the longitudinal slot, the largest width of the longitudinal slot in the region of the bulges being in a ratio to the normal width of the longitudinal slot of about 1.25: 1.

Die die Ausbauchungen bzw. Erweiterungen gegeneinander abgrenzenden Nasen befinden sich nach Anspruch 7 zweckmäßigerweise in demjenigen Längenbereich des Längsschlitzes, in welchen der Lagerzapfen der Schwenklasche bei Kipp-Schaltstellung der Treibstange gestellt ist.According to claim 7, the lugs delimiting the bulges or extensions are expediently located in the length range of the longitudinal slot in which the bearing pin of the swivel bracket in a toggle switch position of the drive rod is set.

Die Erfindung ist nach Anspruch 8 weiterhin dadurch gekennzeichnet, daß die Schenkel der Biegestabfeder einen relativ zur Ebene der Stulpschiene hochkant stehenden Rechteckquerschnitt aufweisen und aus verschleißfestem Material, z.B. federhartem Stahl, bestehen.The invention is further characterized according to claim 8, characterized in that the legs of the flexible rod spring have an upright rectangular cross section relative to the plane of the faceplate and made of wear-resistant material, e.g. spring hard steel.

Schließlich ist eine erfindungsgemäße Kippriegelvorrichtung nach Anspruch 9 auch noch dadurch gekennzeichnet, daß in das untere Ende des Längsschlitzes der Stulpschiene ein gewöbt konturierter Höcker vorspringt.Finally, a tilt lock device according to the invention is also characterized in that a curved contoured protrusion protrudes into the lower end of the longitudinal slot of the faceplate.

Die Schwenklasche 5 ist dabei an der Stulpschiene 6 eines sogenannten Kantengetriebes schiebbar geführt, an deren Rückseite sich eine Treibstange 7 befindet.The swivel bracket 5 is slidably guided on the faceplate 6 of a so-called edge gear, on the back of which there is a drive rod 7.

Mit dieser Treibstange 7 ist ein Verschlußzapfen 8 verbunden, welcher in der Verschlußlage des Flügels 1 zwischen zwei Stege 9 der Kippriegelplatte 4 eingeschoben werden kann und dadurch den Flügel 1 in seiner Verschlußlage am feststehenden Rahmen 2 verriegelt.With this drive rod 7, a locking pin 8 is connected, which can be inserted in the closed position of the wing 1 between two webs 9 of the rocker plate 4 and thereby locks the wing 1 in its closed position on the fixed frame 2.

Die Schwenklasche 5 ist unter Vermittlung des Verschlußzapfens 8, und zwar durch einen diesen tragenden Schaft 10 gelenkig mit der Treibstange 7 verbunden.The swivel tab 5 is articulated to the drive rod 7 by means of the locking pin 8, namely by a shaft 10 carrying this.

Nahe ihrem unteren Ende trägt die Schwenklasche 5 einen Profilnocken 11, welcher eine zu seiner Längsmittelebene symmetrische Form, beispielsweise Vierkantform, aufweist und mit einer Tasche 12 an der Kippriegelplatte 4 zusammenwirkt, welche ebenfalls eine zu einer Längsmittelebne symmetrische sowie zumindest in ihrem oberen Teil nach abwärts konvergierende Keilform aufweist.Near its lower end, the swivel bracket 5 carries a profile cam 11, which has a shape symmetrical to its longitudinal center plane, for example a square shape, and interacts with a pocket 12 on the rocker bar plate 4, which also has a symmetry to a longitudinal center plane and at least in its upper part downwards has a converging wedge shape.

Der untere enge Teil 13 der Tasche 12 ist in seinen Abmessungen mit geringem Spiel auf die Umrißform des Profilnockens 11 abgestimmt, während der obere, sich keilförmig erweiternde Teil 14 derselben von zwei gewissermaßen als Einschnürungen wirkenden Nasen 15 begrenzt wird.The dimensions of the lower, narrow part 13 of the pocket 12 are matched to the outline shape of the profile cam 11 with little play, while the upper, wedge-shaped part 14 thereof is delimited by two lugs 15, which act as constrictions.

Zwischen den Nasen 15 hindurch wird der Profilnocken 11 mit Hilfe der ihn tragenden Schwenklasche 5 in die Tasche 12 eingeschoben, solange sich der Flügel 1 noch in der Verschlußlage am feststehenden Rahmen 2 befindet, wie das aus Fig. 1 hervorgeht. Sodann kann der Flügel 1 in Kippstellung gebracht werden, wobei die Schwenklasche 5 aus ihrer in Fig. 1 gezeigten Parallellage zur Stulpschiene 6 in einer aus Fig. 2 erkennbare Ausschwenklage gebracht wird. Es hebt sich hierbei der Profilnocken 11 geringfügig aus dem unteren Teil 13 der Tasche 12 an und legt sich unterhalb der Nocken 15 gegen die Flanken der Erweiterung 14 der Tasche 12.Between the lugs 15, the profile cam 11 is inserted into the pocket 12 with the aid of the pivoting flap 5, as long as the wing 1 is still in the closed position on the fixed frame 2, as can be seen in FIG. 1. The wing 1 can then be brought into the tilted position, the swivel bracket 5 being brought from its parallel position shown in FIG. 1 to the faceplate 6 in a swiveled-out position which can be seen in FIG. 2. Here, the profile cam 11 lifts slightly out of the lower part 13 of the pocket 12 and lies below the cam 15 against the flanks of the extension 14 of the pocket 12.

Die obere Querkante 16 des Profilnockens 11 schwenkt dabei unter eine der Nasen 15 und verhindert dadurch eine unbeabsichtigte oder unerwünschte Fehlschaltung der Kippriegelvorrichtung 3 über die Treibstange 7.The upper transverse edge 16 of the profile cam 11 pivots under one of the lugs 15 and thereby prevents an unintentional or undesirable incorrect switching of the rocker bar device 3 via the drive rod 7.

Durch die symmetrische Formgebung aller Teile der Kippriegelvorrichtung 3 zuvorbestimmten Längsmittelebenen ist eine beliebige Rechts- und Links verwendung derselben sichergestellt, obwohl die Tasche 12 einstückig an die Kippriegelplatte 4 angeformt ist.Due to the symmetrical shape of all parts of the rocker bar device 3 predetermined longitudinal center planes any right and left use of the same is ensured, although the pocket 12 is integrally formed on the rocker bar plate 4.

Der den Verschlußzapfen 8 und die Schwenklasche 5 mit der Treibstange 7 verbindende Schaft 10 durchgreift einen Längsschlitz 17 in der Stulpschiene 6, dergestalt, daß er zwischen den beiden Längskanten 18 desselben über dessen ganze Länge hinweg verschiebbar ist.The locking pin 8 and the swivel tab 5 with the drive rod 7 connecting shaft 10 passes through a longitudinal slot 17 in the face plate 6, such that it is displaceable between the two longitudinal edges 18 of the same over its entire length.

Etwa über das obere Drittel der Gesamtlänge des Längsschlitzes 17 hinweg haben dessen Längskanten 18 einen geradlinigen, parallelen Verlauf 18a, während sie in dem daran nach unten anschließenden Längenbereich nacheinander jeweils mit einer Ausbauchung bzw. Erweiterung 18b, einer Nase 18c und einer weiteren Ausbauchung bzw. Erweiterung 18d versehen sind.Approximately over the upper third of the total length of the longitudinal slot 17, its longitudinal edges 18 have a straight, parallel course 18a, while in the length region adjoining it downwards they are successively with a bulge or extension 18b, a nose 18c and a further bulge or Extension 18d are provided.

Während die Nasen 18c jeweils so gestaltet sind, daß ihr Scheitel in geradliniger Verlängerung mit den parallelen Abschnitten 18a der Längskanten 18 liegt, sind die Ausbauchungen bzw. Erweiterungen 18b und 18d so gestaltet, daß an ihrer tiefsten Stelle der Längsschlitz 17 jeweils eine Breite hat, die im Verhältnis zur Breite im Bereich der parallelen Längenabschnitte 18a etwa bei 1,25 : 1 liegt.While the lugs 18c are each designed so that their apex is in a straight extension with the parallel sections 18a of the longitudinal edges 18, the bulges or extensions 18b and 18d are designed such that the longitudinal slot 17 has a width at its lowest point, which is about 1.25: 1 in relation to the width in the area of the parallel longitudinal sections 18a.

Die Ausbauchungen bzw. Erweiterungen 18b der Längskanten 18 schließen sich an deren Bereiche 18a zunächst unter einem spitzen Winkel geradlinig divergierend, während sie daran anschließend von der tiefsten Stelle aus mit einem relativ großen Radius konvergierend zum Scheitel der Nase 18c hin geführt sind.The bulges or extensions 18b of the longitudinal edges 18 initially close at their regions 18a in a straight line diverging at an acute angle, while then they converge from the deepest point with a relatively large radius to the apex of the nose 18c.

Die Ausbauchungen bzw. Erweiterungen 18d erstrecken sich unter spitzwinklig divergierendem Verlauf wiederum vom Scheitel der Nasen 18c weg nach unten, wobei jedoch der Neigungswinkel beträchtlich größer ausgeführt ist als im Bereich der geradlinig divergierenden Abschnitte der Ausbauchungen bzw. Erweiterungen 18b.The bulges or extensions 18d again extend downward from the apex of the lugs 18c with an acute-angled diverging course, but the angle of inclination is considerably larger than in the region of the straight-line diverging sections of the bulges or extensions 18b.

Andererseits haben aber die Ausbauchungen bzw. Erweiterungen 18d nur einen Bruchteil der Länge der Ausbauchung 18b.On the other hand, they have bulges or extensions 18d only a fraction of the length of the bulge 18b.

Die besondere Ausgestaltung des Längsschlitzes 17 in der Stulpschiene 6 ist deutlich in Fig. 4 der Zeichnung zu sehen. Dabei ist auch erkennbar, daß die Ausbauchungen bzw. Erweiterungen 18d mit relativ großen Übergangsradien in einen Höcker 18e auslaufen, welcher in das untere Ende des Längsschlitzes 17 der Stulpschiene mit leichter Wölbung vorspringt.The special design of the longitudinal slot 17 in the faceplate 6 can be clearly seen in Fig. 4 of the drawing. It can also be seen that the bulges or extensions 18d end with relatively large transition radii in a hump 18e which projects into the lower end of the longitudinal slot 17 of the faceplate with a slight curvature.

In den Längsschlitz 17 der Stulpschiene 6 ist eine Biegestabfeder 19 eingesetzt, die zwei durch einen Steg 19a einstückig miteinander verbundene Schenkel 19b und 19c aufweist.A bending rod spring 19 is inserted into the longitudinal slot 17 of the faceplate 6 and has two legs 19b and 19c which are integrally connected to one another by a web 19a.

Die Biegestabfeder 19 hat dabei einen rechteckigen Materialquerschnitt und ist so in den Längsschlitz 17 eingesetzt, daß dieser Rechteckquerschnitt quer zur Ebene der Stulpschiene 6 hochkant steht und um ein geringes Maß, beispielsweise um höchstens 1 mm über die äußere Breitseite der Stulpschiene 6 vorsteht. Ihre übrige Querschnittshöhe von mindestens 2 mm wird hingegen im Längsschlitz 17 über die Materialdicke der Stulpschiene 6 hinweg aufgenommen.The bending rod spring 19 has a rectangular material cross section and is inserted into the longitudinal slot 17 so that this rectangular cross section is perpendicular to the plane of the faceplate 6 and protrudes by a small amount, for example by a maximum of 1 mm beyond the outer broad side of the faceplate 6. Their remaining cross-sectional height of at least 2 mm, however, is received in the longitudinal slot 17 over the material thickness of the faceplate 6.

Die Biegestabfeder 19 hat in jedem Falle eine solche Anordnung innerhalb des Längsschlitzes, daß ihr Steg 19a an dessen oberem Ende eine Stützanlage findet, während die freien Enden ihrer Schenkel 19b und 19c dem unteren Ende des Längsschlitzes 17 zugewendet sind und in unmittelbarer Nachbarschaft des Höckers 18e zu liegen kommen.The bending rod spring 19 in any case has such an arrangement within the longitudinal slot that its web 19a is supported at its upper end, while the free ends of its legs 19b and 19c face the lower end of the longitudinal slot 17 and in the immediate vicinity of the bump 18e come to rest.

Ihre seitliche Abstützung erhalten die beiden Schenkel 19b und 19c der Biegestabfeder 19 einerseits an den zueinander parallel verlaufenden Abschnitten 18a im oberen Drittel des Längsschlitzes 17 sowie andererseits mit gewissem Abstand oberhalb ihrer freien Enden nochmals durch die Nasen 18c.The two legs 19b and 19c of the bending rod spring 19 receive their lateral support on the one hand at the mutually parallel sections 18a in the upper third of the longitudinal slot 17 and on the other hand again at a certain distance above their free ends by the lugs 18c.

Im entspannten, als geradlinig verlaufenden Zustand liegen jedoch die Schenkel 19b und 19c der Biegestabfeder 19 im Bereich der Ausbauchungen bzw. Erweiterungen 18b und 18d des Längsschlitzes 17 nicht an dessen Längskanten 18 an.In the relaxed, straight-line state, however, the legs 19b and 19c of the bending rod spring 19 do not rest on the longitudinal edges 18 in the region of the bulges or extensions 18b and 18d of the longitudinal slot 17.

Die einander zugewendeten Innenflächen beider Schenkel 19b und 19c der Biegestabfeder 19 bilden auch die Seitenführung für den als Lagerzapfen für die Schwenklasche mitbenutzten Schaft 10 des Verschlußzapfens 8 und tragen dabei - wegen ihrer glatten Oberflächen und ihrer großen Härte - zur Minimierung der Verschleißerscheinungen zwischen den zueiander beweglichen Funktionsteilen bei.The mutually facing inner surfaces of both legs 19b and 19c of the bending rod spring 19 also form the side guide for the shaft 10 of the locking pin 8 which is used as a bearing pin for the pivoting lug and, because of their smooth surfaces and their great hardness, contribute to minimizing the signs of wear between the mutually movable ones Functional parts at.

Mit den beiden Schenkeln 19b und 19c der Biegestabfedern 19 wirkt die Schwenklasche 5 über zwei in ihre Rückseite eingeformte, parallel zueinander verlaufende Längsnuten 20a und 20b zusammen, in welche die Schenkel 19b und 19c formschlüssig passend eingreifen. Bei einer Verschiebung des Lagerzapfens bzw. Schaftes 10 mittels der Treibstange 7 entlang der Stulpschiene 6 verschiebt sich dabei die Schwenklasche 5 mit ihren Längsnuten 20a und 20b entlang den Schenkeln 19b und 19c der Biegestabfeder 19. In der gänzlich nach oben geschobenen Stellung der Schwenklasche stehen dabei die Schenkel 19b und 19c der Biegestabfeder 19 zumindest nahezu auf der ganzen Länge der Schwenklasche 5 mit deren Längsnuten 20a und 20b in Halte-und Führungseingriff. In der mittleren Schaltstellung der Schwenklasche 5 erstreckt sich der Führungseingriff zwischen den Schenkeln 19b und 19c der Biegestabfeder 19 sowie den Längsnuten 20a und 20b der Schwenklasche 15 noch über mehr als deren halbe Länge. Die Schenkel 19b und 19c dienen hierbei als Parallelführung für die Schwenklasche 5. Ist hingegen die Schwenklasche 5 in ihre untere Schaltstellung gebracht (siehe Fig. 1, 2 und 4) dann stehen die beiden Schenkel 19b und 19c der Biegestabfeder 19 nur noch in dem dem Lagerzapfen bzw. Schaft 10 benachbarten Längenbereich der Schwenklasche 5 mit deren Längsnuten 20a und 20b in Formschlußeingriff.The swivel bracket 5 interacts with the two legs 19b and 19c of the bending rod springs 19 via two longitudinal grooves 20a and 20b which are formed in the back and run parallel to one another and into which the legs 19b and 19c engage in a form-fitting manner. When the bearing pin or shaft 10 is displaced by means of the drive rod 7 along the faceplate 6, the swivel bracket 5 with its longitudinal grooves 20a and 20b is displaced along the legs 19b and 19c of the flexible rod spring 19. The swivel bracket is in the fully pushed-up position the legs 19b and 19c of the bending rod spring 19 at least almost over the entire length of the swivel bracket 5 with its longitudinal grooves 20a and 20b in holding and guiding engagement. In the middle switching position of the swivel bracket 5, the guide engagement between the legs 19b and 19c of the flexible rod spring 19 and the longitudinal grooves 20a and 20b of the swivel bracket 15 extends over more than half their length. The legs 19b and 19c serve here as a parallel guide for the swivel bracket 5. On the other hand, if the swivel bracket 5 is brought into its lower switching position (see FIGS. 1, 2 and 4), then the two legs 19b and 19c of the bending rod spring 19 are only in that Bearing pin or shaft 10 adjacent length range of the swivel bracket 5 with its longitudinal grooves 20a and 20b in positive engagement.

In der unteren Schaltstellung der Schwenklasche 5 liegt deren Lagerzapfen bzw. Schaft 10 mit seiner Längsachse auf einer Ebene, die etwa mit den Scheiteln der beiden Nasen 18c nahe dem unteren Ende des Längsschlitzes 17 in der Stulpschiene 6 zusammenfällt. Wird nun durch das Kippöffnen des Flügels 1 die über ihren Profilnocken 11 mit der Tasche 12 der Kippriegelplatte 4 in Eingriff stehende Schwenklasche 5 aus ihrer Parallellage zur Stulpschiene 6 in eine Schräglage hierzu gebracht, dann stellt sich eine elastische Verformung an den beiden Schenkeln 19b und 19c der Beigestabfeder 19 ein. Diese wird über die in der Unterseite der Schwenklasche 5 befindlichen Längskanten 20a und 20b im Zusammenwirken mit den Nasen 18c an den Längskanten 18 des Längsschlitzes 17 der Stulpschiene 6 bewirkt, wie das die Fig. 4 erkennen läßt. Die Winkelverlagerung der Schwenklasche 5 relativ zur Stulpschiene 6 findet daher gegen die Wirkung einer relativ starken Rückstellkraft der Schenkel 19b und 19c der Biegestabfeder 19 statt. Hierdurch wird bei jeder Kippöffnungslage des Flügels 1 relativ zum feststehenden Rahmen 2 eine spiel- und klapperfreie Kipphalterung über die Kippriegelvorrichtung 3 herbeigefügt.In the lower switching position of the swivel bracket 5, its journal or shaft 10 lies with its longitudinal axis on a plane which coincides approximately with the apexes of the two lugs 18c near the lower end of the longitudinal slot 17 in the faceplate 6. If the pivoting flap 5, which is in engagement with the pocket 12 of the rocker lock plate 4 via its profile cams 11, is brought into an inclined position from its parallel position to the faceplate 6 by the tilt opening of the wing 1, then an elastic deformation occurs on the two legs 19b and 19c the beige rod spring 19. This is effected via the longitudinal edges 20a and 20b located in the underside of the swivel bracket 5 in cooperation with the lugs 18c on the longitudinal edges 18 of the longitudinal slot 17 of the faceplate 6, as can be seen in FIG. 4. The angular displacement of the swivel bracket 5 relative to the faceplate 6 therefore takes place against the action of a relatively strong restoring force of the legs 19b and 19c of the flexible rod spring 19. As a result, with each tilt opening position of the wing 1 relative to the fixed frame 2, a play and rattle-free tilt bracket is brought about via the tilt latch device 3.

Die Ausbauchungen bzw. Erweiterungen 18b und 18d an den Längskanten 18 des Längsschlitzes 17 der Stulpschiene lassen die aus der Winkelverlagerung der Schwenklasche 5 relativ zur Stulpschiene 6 resultierenden Biegeverformungen an den Schenkeln 19b und 19c der Biegestabfeder 19 in dem notwendigen Ausmaß zu und sicheren dadurch dauerhaft die ordnungsgemäße Funktion der gesamten Kippriegelvorrichtung 3.The bulges or extensions 18b and 18d on the longitudinal edges 18 of the longitudinal slot 17 of the faceplate allow the bending deformations on the legs 19b and 19c of the bending rod spring 19 resulting from the angular displacement of the swivel bracket 5 relative to the faceplate 6 to the extent necessary and thereby permanently secure them proper function of the entire tilt lock device 3.

Der in das untere Ende des Längsschlitzes 17 der Stulpschiene 6 mit einem Wölbungsradius vorspringende Höcker 18e stellt sicher, daß die freien Enden der beiden Schenkel 19b und 19c der Biegestabfeder 19 immer wieder sicher in ihre ordnungsgemäße Ruhelage zurückkehren können, sobald die Schwenklasche 5 ihre Parallellage zur Stulpschiene 6 einzunehmen sucht.The protruding into the lower end of the longitudinal slot 17 of the faceplate 6 with a radius of curvature hump 18e ensures that the free ends of the two legs 19b and 19c of the bending rod spring 19 can always safely return to their proper rest position as soon as the swivel tab 5 to its parallel position Face plate 6 tries to take.

Abschließend sei noch erwähnt, daß die Schwenklasche 5 an ihrem oberen Ende noch mit einer Ausklinkung 21 vesehen ist, die relativ zu den Längs nuten 20a und 20b in der Rückseite der Schwenklasche 5 eine solche Anordnung und Ausbildung hat, daß sie in der oberen Schaltstellung der Schwenklasche 5 problemlos den die beiden Schenkel 19b und 19c einstückig miteinander verbindenden Steg 19a der Schenkelfeder 19 aufnehmen kann.Finally, it should also be mentioned that the swivel bracket 5 is still provided at its upper end with a notch 21, which has relative to the longitudinal grooves 20a and 20b in the rear of the swivel bracket 5 such an arrangement and design that they in the upper switching position of the Swivel bracket 5 easily the two Schen kel 19b and 19c integrally connecting web 19a of the leg spring 19 can accommodate.

Die vorstehend beschriebene Ausgestaltung einer Kippriegelvorrichtung 3 für Drehkippflügel-Fenster und - Türen od. dgl. hat den besonderen Vorteil, daß alle funktionsnotwendigen Bauteile mit relativ geringem Aufwand aus Festigkeitsmaterial, insbesondere Stahl, hergestellt werden können, so daß eine hohe Funktionssicherheit und Verschleißfestigkeit bei geringstmöglichem Einbauraum erreicht wird. Darüberhinaus ist dann auch die Möglichkeit gegeben, die einzelnen Teile der Kippriegelvorrichtung aus nicht rostenden Stahlqualitäten zu fertigen und dadurch den Einsatz der Beschläge auch in aggressiver Umgebung zu ermöglichen.The above-described configuration of a toggle latch device 3 for tilt-and-turn windows and doors or the like has the particular advantage that all the components required for the function can be produced from strength material, in particular steel, with relatively little effort, so that a high degree of functional reliability and wear resistance with the least possible Installation space is reached. In addition, it is then also possible to manufacture the individual parts of the toggle lock device from stainless steel grades, thereby enabling the fittings to be used even in an aggressive environment.
